2 days until I leave my job and I am assigned a large, legal requirement task to complete, with no time to plan or opportunity to hand over the work. No way it will be done in time, and no teamwork, so no one else will be up to speed on it when I leave, and I daresay I'll be blamed for it not working to their 2 sentence specification! Yup, that's why I'm leaving folks!

2 days huh..? I think it might be time to catch some cold or smth.. for 2 days. (1) you do not have to deal with this nonsense and (2) manager will pass the task over to someone else to work on, ergo you will not be the one to blame for unfinished task and others will not have to rely on someone who's leaving tomorrow. I see it as a win-win for both you and your workplace.

Things you have to do to keep the show on the road when your management is so amateur...
